Abstract
A flywheel assembly has a first flywheel which is detachably connected to the crankshaft of a combustion engine, a second flywheel which can be rotated relative to the first, and a torque transformer, such as a hub disc, which is located in a chamber between the two flywheels, which chamber is filled with a viscous medium and which torque transformer is equipped with a torsion damping unit. The chamber is defined on that side facing the second flywheel by a cover plate, which encloses an air channel between it and the second flywheel, which air channel extends radially outward from a ventilation opening in the second flywheel. The torque transformer is provided radially outward from the ventilation opening with an annular surface, which annular surface extends preferably in the axial direction. The cover plate extends with its radially inward end in the radial direction to the annular surface and in the axial direction to the radially outer portion of the torque transformer, whereby the annular surface defines the maximum radial distance from the torque transformer to the ventilation opening for the change of direction of the air channel.
